How does nuclear fusion create elements inside stars?
Nuclear fusion in stars involves the process of combining lighter elements, such as hydrogen, to form heavier elements, such as helium. As these elements fuse together, they release energy in the form of heat and light. Over time, through a series of fusion reactions, heavier elements are synthesized, up to iron, in the core of stars.
Is a particle accelerator used to accelerate particles at high speeds until the particles fuse together and create a new elements?
Not exactly.Accelerate particles to high speeds: yes.Create new elements: it is not new elements, but new particles that are created.Fuse together: this is not so much about particles fusing together; rather, the new particles are created from the energy of the impact. Remember that every energy has a mass equivalent. For example, the LHC is planned to increase its energy to 6.5 TeV per beam, meaning that two particles - two protons for example - will collide at a combined energy of 13 TeV. This corresponds to a mass of about 14,000 protons. This makes it possible to create new particles, including particles that are quite massive.
Why can't a star fuse chemical elements beyond iron?
It sure can - and some stars do, to a minor degree. However, it can no longer gain energy from this fusion - it costs energy to create heavier elements. --- To fuse Iron, you would need a huge amount of heat and pressure, higher than what can be provided by even the massive stars is existence. The upper limit of a stars mass puts this limit on what materials it can fuse. Elements heavier than Iron are created during a supernova explosion, the death of a massive star.
What is the most stable nuclei in the universe?
Helium is the most stable element. All noble gases are "stable", but helium has the least amount of electrons, this causes it to be less affected by London dispersion forces (Vanderwal). This is why helium has the lowest boiling point of all elements.
What is the formula for calculating the mass loss of nuclear fusion?
Fusion occurs when elements are pushed together to form a third element. Like two Hydrogen atoms fused together to form a Helium atom. There are formulas that tell you how much energy, or force, has to be used to get elements to fuse together, because it is extremely difficult to get this to happen. Also, when two elements fuse together the final element has less mass then the original two elements. This loss in mass comes out as energy and there are formulas that tell you how much energy will come out. So there are several formulas dealing with different aspects of fusion, but not a single formula that tells you everything you might want to know about fusion.

Why do fuel is required for fusion?
Technically, any elements less massive than iron can fuse together; however, practically it is easier to fuse the lightest elements (Hydrogen, Helium...), which also give higher energy yields. Any elements which are heavier than iron (or are iron) will not fuse, and instead decay via nuclear fission.
What element is created when hydrogen atoms fuse together in the sun and core?
When hydrogen atoms fuse together in the sun's core, they create helium. This process releases energy in the form of light and heat, which provides the sun's power.
Why do stars have gas in them?
there made of gas not have it in them and they use it to fuse into new elements to get energy from it
How do atoms make stars burn?
The enormous heat and pressure at the center of a star causes atoms to fuse together, releasing enormous amounts of energy. Most stars fuse hydrogen, but larger stars that have exhausted the hydrogen in their cores may fuse heavy elements.
What event is believed to create elements heavier than iron?
The explosion of a supernova. Some astrophysicists don't believe that even THAT would suffice to make some of the very heavy elements such as gold or uranium; they believe that only the collision of two neutron stars would release enough energy to do that. The problem is the "packing fraction" curve. Two atomic nuclei can smash into each other at high energy and release a little bit of energy as the nuclei come together, or "fuse". When two or more hydrogen atoms smash into each other in the cores of stars, they fuse into helium, and we call this "nuclear fusion". As we smash heavier and heavier elements together, they release smaller and smaller amounts of energy in fusing - until we get to iron. Once you start fusing elements together to get stuff heavier than iron, you have to PROVIDE energy to complete the reaction. Think of the packing fraction curve as a valley, with iron at the bottom of the valley. As you roll your bike down the hill from one side, you can coast because gravity is providing energy. Once you pass iron (at the bottom of the hill) you need to start putting in your OWN energy, by pedaling.
Why can't iron be fused to release energy?
Iron cannot be fused to release energy because it requires more energy to fuse iron atoms together than the energy that is released in the process. This is due to the fact that iron has the highest binding energy per nucleon of any element, making it less energetically favorable to fuse compared to lighter elements like hydrogen.

What is produced when elements fuse in the sun?
Both energy (sunlight) and helium are produced when hydrogen fuses together. This also what happened when the US used atomic weapons on Japan in WW2.
